What is the greenhouse effect and how is it related to climate change?
What will be an ideal response?
?The greenhouse effect is responsible for keeping the earth at a moderate temperature capable of supporting life. Short-wave radiation from the sun penetrates our atmosphere, strikes the earth, and is reflected, in longer-wave radiation (infrared) back into the atmosphere where certain gases, including water vapor (H2O), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), tend to keep it within the troposphere. However, with increasing industrialization, humans have increased the amount of these greenhouse gases in the atmosphere to the point where the atmosphere is heating up, thus bringing about climate change.
